About CSS Isolation

The isolation property determines whether an element must create a new stacking context.

When set to isolate, it creates a new stacking context, preventing blend modes and z-index from affecting elements outside this context.

This is particularly useful when working with mix-blend-mode, background-blend-mode, and complex z-index hierarchies.
